ios - UIImagePickerController 与 Cocos2D 2.0

Question

我想使用 UIImagePickerController，我找到了这个例子

添加到.h

@interface MenuScene : CCLayer <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{
    UIWindow *window;
    UIImage *newImage;
}

添加到.m

-(void)pickPhoto:(UIImagePickerControllerSourceType)sourceType{    
    UIImagePickerController *picker = [[UIImagePickerController alloc]init];
    picker.delegate = self;
    picker.sourceType = sourceType;
    picker.wantsFullScreenLayout = YES;
    [picker presentViewController:picker animated:NO completion:nil];
    [[[CCDirector sharedDirector] view] addSubview:picker.view];
}

-(void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingMediaWithInfo:(NSDictionary *)info{
    newImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    [picker dismissViewControllerAnimated:YES completion:nil];
    [picker.view removeFromSuperview];
    [picker release];
    CCSprite *imageFromPicker = [CCSprite spriteWithCGImage:newImage.CGImage key:@"ImageFromPicker"];
}

我尝试调用[self pickcPhoto:UIImagePickerControllerSourceTypeCamera]，它在[picker presentViewController:pickerAnimated:NO Completion:nil];处崩溃，并显示消息

由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因:“应用程序试图在自身上呈现模态视图 Controller 。呈现 Controller 是 . '

我正在 iOS 6 上使用 Cocos2d v2 进行测试，我将感谢您的任何建议。

更改代码如下，只需使用在此行中编辑注释更改行，或者可以复制该行

-(void)pickPhoto:(UIImagePickerControllerSourceType)sourceType{    
    UIImagePickerController *picker = [[UIImagePickerController alloc]init];
    picker.delegate = self;
    picker.sourceType = sourceType;
    picker.wantsFullScreenLayout = YES;
    [self presentViewController:picker animated:NO completion:nil]; //Edit in this line
    [[[CCDirector sharedDirector] view] addSubview:picker.view];
}

-(void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingMediaWithInfo:(NSDictionary *)info{
    newImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    [self dismissViewControllerAnimated:YES completion:nil]; //Edit in this line
    [picker.view removeFromSuperview];
    [picker release];
    CCSprite *imageFromPicker = [CCSprite spriteWithCGImage:newImage.CGImage key:@"ImageFromPicker"];
}
